IMPROVEMENT IN DOUBLE-ACTING PUMPS.

Specification forming part of Letters Patent No. 197,809, datedDecember 4, 11.877; application led August 10, 1877.

To all whom it may concern:

Beit known that I, JOHN S. ADAMS, of Elgin, in the county 'of Kane, and in the State of Illinois, have invented certain new anduseful Improvements in Pumps and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a perspective view of my improved pump arranged as a surface or platform pump. Fig. 2 is a like View of the same arranged as a submerged pump. Figs. 3 andl 4 4are perspective views of `opposite sides of passes through. Fig. l0 is a perspective view of Va piston, a portion of the head and packing being broken away; and Fig. ll is a longitud- I inal section of the same.

parts in each of the figures.

The design of myinvention is to simplifyy the construction and increase 4the efficiency same easily adjustable as surface or submerged pumps to 'which end it consists, principally,

in the means employed for operating the ref ciprocating pistons, substantially as is hereinafter specified.

as and for the purpose hereinafter shown.

for the purpose hereinafter set forth.

It consists,'further, in the construction of the valves and seats, and their arrangement within the pump', substantially as and for the i purpose hereinafter shown and described.

It consists, further, in the peculiar construcfled.

It consists, further, in the constructionl of the supporting-base, and its combination with the pump, substantially as and for the purpose hereinafter shown.

It consists, further, in the peculiar construction of the standard at the point where the pivotal bolt for the walking-beam passes, sub- Y stantially as and for the purposeV hereinafter set forth.

It consists, further, in the construction of the tension-blocks, and their combination with lhe walking-beam and tension-rods, substantially as and for the purpose hereinafter shown and described. p

It consists, finally, in the means employed for connecting a hose toor with the dischargepipe of the pump, substantially as is hereinafter specified..

In the annexed' drawings, A and A represent two cylinders, which have the same axis, are open at their outer ends, and at their inner ends open into a chamber, B,that is open at its upper side, said chamber being cast with and forming a part of said cylinders.

Below the cylinders A and chamber B is a pipe, C, which extends from end to end of said Letters of like name and kind refer to like cylinders, is cast upon the same and said chamber, and has open ends, and at its lower side, at its longitudinal center, is provided with a bran ch c, that extends vertically downward. p.

Formed upon the upper side of the cylinders A is a second pipe, D, which, over the chamber B, is arched, as seen in Fig. 4, and .at its ends, which coincide with the ends of said cylinders, is expanded laterally and vertically,

so as to formy at such points a chamber, d.

It consists, further, in the mean-s employed l for 4operating the pump when `submerged orgv set belowthe operating-platform, substantially 1 From the upper side, at the longitudinal center of said pipe, a pipe, E, extends upward to and is connected with an- .air-chamber, F, and

from' the latter another pipe, G, extends upl It consists, further, in the construction of i the casing of the pump, substantially as and wardto any desired pointr at which water is to be discharged.

The outer ends of each cylinder A and of the pipes C and D are inclos'ed by means of a head, H, which, opposite` theV said pipe G, is provided with a recess, h, that corresponds in size to the chamber d ofthe pipe D, from which recess extends upward within said head a pipe, h,.that connects with said chamber d.

Opposite the cylinder A each head H is recessed slightly, to correspond with the interior of the same, while the recess h extends` upward to said" cylinder, 'and furnishes a communication between the. interior of the same and the pipes C, h', and D.

pressure against said seat bymeans of a spring or springs, i, that is arranged toipress against its outer side, the arrangement being such as to cause said valve to swing outward and up-.

ward in uncovering the end of said pipe.

The upper end of each pipe h within the head H, which open inward into the chamber d, is inclosedby l means of a valve, I, whichA is the exact counterpart of the valve described, and swings inward and upward in uncovering said pipe.

Within each cylinder A is fitted a piston, K, which is connected with the opposite pis-v ton by means of a rod, L, so as to move simultaneously with the same.

' The central portion of the piston-rod L is flattened, so as vto increase its vertical dimensions, and within such portionis formed a vertical'slot, l, which is `open at its upper end.

Motion is imparted yto the pistons K by means of a rock-shaft, M, which is journaled horizontally within the upper portion of the chamber B, and is provided with two arms, m, that extend downward upon each side of the piston-rod L, and are connected by a pin, m', which passes through the slot l. Awasher, m, is placed upon said pin m upon each side of said piston-rod, and, tting into a recess, l', that is formed upon each side of the latter, forms a rolling bearing, and receives the pressure as said rock-shaft is oscillated upon its bearing.

From the upper side, at one end of the roekshaft M, an arm, fm", extends upward, outward, and then upward, and at its upper end is provided with a socket for the reception of a bar or lever, N, that is employed for operating the pump. A l If, now, the pump is secured upon a suitable support, and the pipe c connected with a 'supply of water, the oscillation of the operating-lever N will cause the pistons to be moved back and forth within their cylinders, and each of said pistons to alternately ll its cylinder with water through the pipes c and C and recess h, and to expel said water through said recess h, pipe h', chamber d, pipe l), and pipe' E, duringV which operation the lower valves I will permit water to enter the recess h from the pipe 0,-but not to move in an opposite direction, while the upper valves I will permit water to'pass from the pipe h into the chamber d while operating to prevent the return of said water.

It will be seen that water passing through each valve is given a downward direction as it leaves the same, bywhich means sand passing into the pump will be prevented from settling, and, by being kept in motion, will be carried upward by the current of water until it passes from the pump.r

The pistons K are packed by means of a ring of metal, k, which is divided transversely ato'i'ie point, is somewhat larger than the cyl- Yinder, and is sprung into the same, while outside of said ringV is placed a ring or covering of leather, rubber, or other like iiexible material, which is divided transversely at one point upon a zigzag line, that causes one portion of .each end to lap by the corresponding portion of the opposite end of said flexible ring. This packing is durable and efficient, and when worn out can be easily and quickly replaced by any person capable of operating a pump.

When the pump is for use in a Well I employ a support, which consists of a Haring,

cup-shaped base, O, and a pointed spur, o,

that projects downward from the lower side of the same.

The supporting-base O is placed in position by driving its spur downward until the lower end of said base rests upon or is sunk slightly into the .soil at the bottom of the well, after which a cylindrical strainer, l?, is placed upon the lower end of the inlet-pipe c, and the lower end of said strainer caused to iit into a corresponding recess that isprovided in said base, when, as shown in Figs. 2 and 5, the whole weight of the pump will be sustained by said base, and said pump prevented from moving laterally, while, from the shape of the former, the water at the bottom of the well will be prevented from becoming riled in consequence of disturbance of the soil at such point.

When the pump is thus submerged, or is placed below the operating-platform, it is op-v erated bythe following-described means: The discharge-pipe Gr is provided, at a level with the surfaceof the ground, with a iiange, G', that extends horizontally outward, and furnishes a `means whereby said pipe may be secured to or upon a platform, Q. At a suitable distance above the platform Q the pipe or standard G is provided with a cylindrical enlargement, g, which has its axis placed horizontally, and around such axis is formed an annular opening, g', that communicates with,

andforms a continuation of, the water-passage y within said standard, above and below said boss. Through the otherwise solid axial center of the boss g is provided an opening which receives and contains la bolt, R, that serves as a pivotal bearing for a walkingbeam, S, which beam has a central opening, s, that enables it to be placed over or around said standard. This construction of the standard enables the walking-beam to be easily and strongly pivoted thereto, without interference with'or penetration of the water-channel.

The ends of the walking-beam S are bifurcated, and within each is pivoted a block, T, which, as seen in Figs. 3 and 4, is grooved Vlongitudinally upon its inner side, and is provided near its upper end with ears t, that project inward, and serve as bearings for the reception of the pivotal bolt.

Within the groove t of each block T is placed one end of a tension-rod, U, which is threaded and provided with nuts u at the upper and lower ends of said block, by means of which said rod is secured in place and is adjusted longitudinally.

This construction of the tension-block prevents the tensionrod and the axial bearing of said block from interference with each other, and enables stronger and more durable connections to be made.

The lower end of each tension-rod U is connected with a block, V, which is pivoted within one end of a horizontal bar, mm', which is secured upon the arm m'" of the rock-shaft M in place of the. lever-socket. If, now, the walking-beam S is caused to oscillate upon its pivotal bearing, its motion will be communicated,

4through the rods U, lever mm', and rock-shaft M, to the pistons of the pump, and the latter caused to force water into and through the standard G.

For the operation of the pump by hand, an arm, s', projects upward, outward, and upward from the axial center, at one side of the walking-beam S, and at its upper end is provided with a socket, s, for the reception of the hand-lever N, while for use in connection with a windmill, one of the tension-blocks T is provided with an arm, t, which extends upward, inward, and then upward, and at its upper end has such shape as to permit of the attachment of the vertically-reciprocatin g operating-rod oi' such windmill.

It being often necessary that hose should be attached to the discharge-pipe of a pump, the following-described means for such attachment are provided: The end of the standard G is slightly enlarged, so as to furnish at such point bearing for a packing-gasket, and over such end is iitted a coupling, V, the upper end of which latter is recessed so as to receive the end of said standard. The lower end of the coupling V is grooved circumferentially, so as to permit of the ready attachment of a hose, while at a point near its upper end is provided a cylindrical enlargement, c, through the center of which passes the pivotal bearing fw of a stirrup, W, that at its upper end containsa set-screw, X. The waterchannel Vc of the coupling V passes concentrically around the axis of the enlargement o, so that the pivotal bearing w of the stirrup W does not enter said channel. A spur, g, formed upon the outer side of the standard G at a short distance above its end, receives the merits of my invention, what I claim as new 1s- 1. -In combination with the piston-rod L, provided at 'its longitudinal center with a vertical slot, l, and recesses l', the rock-shaft M,

having the arms m, connected by the pin m',

and the washers m placed upon said bar, substantially as and for the purpose speci fied.

provided with the lever mm', the walkingbeam S, having the arm s s", the tensionblocks T, and the tension-rods U, said parts be ing arranged to operate in the manner and for the purpose substantially as shown.

3. The casing of the pump, consisting of the cylinders A, centralchamber B, inlet-pipe C `c, outlet-pipe D d E, and heads H, which are each provided with a recess, h, andvertical pipe h', substantially as and for the purpose set forth.

4.' In combination with the ends of the pipes Gand h', arranged, respectively, above 6. As` a means or supporting the pump, andpreventing lateral motion of the same lwhen placed at the bottom of a well, the base O, arranged to embrace the strainer l?, and provided with a spur, which projects downward from its lower side, substantially as and for the purpose shown. i

7. The standard G, provided with the cylindrical enlargement g and annular passage g', in combination with the walking-beam S and its pivotal bearing R, substantially as and for the purpose set forth.
